Subject: [PATCH] remove SIGUSR1 escape; pkill <editor> is the standard
 recovery

The SIGUSR1 -> editor_emergency_kill wiring was a contrived escape
hatch. A console user with a stuck editor reaches for kill / pkill /
SIGKILL on the editor, not undocumented signals on the chat client.
editor_emergency_kill() stays for the internal Ctrl-Z abort path.
